auto-extracting archive is potentially a simple, basic form of
installer, most software for creation of installation packages extends
the idea further providing
formats capable of advanced scripting features to generate more complex
and flexible
autoextraction modules to unpack the content and perform other related
operations, suc as conditional extraction of appropriate data,
automatic output path detection, registration of shared files,

advantages and disadvantages </span><br>
            </big></h3>
            <br>
Principle behind self extracting archives is providing the end user of
the appropriate extraction
executable instructions without the need of installing any software,
which brings those advantages over non self extracting archives:<br>
            <ul>
              <li>content and extraction tools are passed as atomic
information</li>
              <li>in order to extract the content, end user needs to
run only a simple subset of instructions, through a minimal user
interface requiring little or no feedback, rather than having to
install and learn to operate a full general purpose archive manager
software</li>
            </ul>
            <h4>Drawbacks of self extracting archives are:</h4>
            <ul>
              <li>being the
extraction module embedded in the archive itself, it represents an
overhead (usually some 10s or 100s of KB), which makes it a noticeable
disadvantage in
the case of small&nbsp; archives</li>
              <li>the sfx archive can be executed only on operating
system platforms capable to run the sfx module - it can still be
operated as a standard archive on other platforms, if suitable software
is available<br>
              </li>
              <li>being the self extracting archive an
executable file, some file sharing platforms - cloud service&nbsp;
providers, e-mail servers - may consider it a security risk and block
the file, preventing it to reach the intended end users.</li>
